3M 16:9 Aspect Ratio Frameless Blackout Privacy Filter for 27 in. Widescreen iMac

3M Privacy Filters provide world-class black out privacy from side views outside the 60 Degree viewing angle, while creating an excellent viewing experience from straight on views. Designed for full screen monitors with flat glass displays, these Privacy Filters are reversible between a glossy side and a glare-reducing matte side that helps reduce reflections and hide fingerprints, so you can enjoy pristine image clarity. The COMPLY Magnetic Attach allows you to quick-click between world-class privacy and screen sharing thanks to ultra strong magnets that click the filter securely into place.
